SOLE-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 483,393, datedSeptember 27', 1892.

Application filed Pehrnaryl, 1892. Serial No. 422,016. (No model.)

To all whom t may concern.:

Be it known that I, JACOB R. SCOTT, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Sole-Trimming Machines, of which thefollowing is a specification.

This invention relates to a machine for reducing the thickness of theedge of a sole for boots or shoes or of any other article of a similarnature.

The peculiar and novel construction of my machine is pointed out in thefollowing speciication and claims and illustrated in the accompanyingdrawings, in which- Figure l represents a face view. aside elevationpartly in section.

In the drawings the letter A designates a frame, which forms thebearings for the shaft B, and on which is firmly secured an arm D, theouter end of which forms the bearing for a pin a, which passes througheyes b h', formed on the upper end of a plate E, which carries the knifeF and the outside gage G, the knife being attached to said plate byascrew c and the outside gage by a screw d. From the top of the plate Eextends a curved arm e, which connects by a rod Il with the outer end ofa lever I, the inner end of which is secured to the frame A by a pivotf, Fig. 2. This lever is exposed to the action of a spring g, and itconnects by a rod h' with a treadle, (not shown,) so that when this rodis forced downward the spring g is compressed, the outer end of thelever I is moved downward, and the plate E, which carries the knife Fand the outside gage Gr, is caused to swing on the pin a in thedirection of arrow l, marked near it, in Fig. 2. \Vhen the lever I isfree to follow the action of the spring g, the plate E swings in thedirection opposite to arrow until the inner end of the arm e strikes aset-screw h, which is tapped into a bracket il, secured to the arm D.

From the curved arm e of the plate E ex` tends a lug j, which is tappedto receive a setscrew k. It' this set-screw is made to bear upon the armD, as shown in Fig. 2, the arm c is locked between it and the set-screwh and the plate E is held rigidly in position; but if the set-screw lois turned back the plate E is Fig. 2 is retained in position by theyielding pressure of the spring g. J is the inside gage, which in theform of a semi-disk and secured to the frame A. The distance between itsinner or upper edge and the knife F is smaller than the distance betweenits outer or lower edge and the knife. The material to be trimmed isplaced between the outside gage G and the inside gage J, the edge ofsaid material being forced in contact with the toothed circumference ofthe feed-wheel C, and if the shaft B is' turned in the direction ofarrow 2, Fig. l, the material to be trimmed is fed forward in thedirection of arrow S, Fig. l, and a portion of said material is cutoff,as indicated in Fig. 2, the thickness of the edge of the material beingreduced to an arnou nt corresponding to the bevel of the face of theinside gage. If the inside gage is mounted on the shaft B and caused torevolve with the same, it forms an auxiliary to the feedwheel C. TheshaftB is geared with the drivingshaft K by cogwvlleels m n, and abelt-pulley c, mounted on the drivingshaft, serves to impart motion tothe same.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination of a rotary feed-wheel C, a bevelfaced gage J,extending round and rotating with the feed-wheel," and a knife F,supported independent of the feedwlxeel and located in front of thelatter for beveling the edge of a sole while such sole is advanced bythe feed-wheel, said knife standing stationary, while the feed-wheelrotates, substantially as described.

2. The combination of a shaftB, a feed-wheel C, mounted on the shaft, abevel-faced inside gage J, extending round and rotating with thefeed-wheel, a knife F, supported independent of the feed-wheel andlocated in front of the latter for beveling the edge of a sole while thefeed-wheel advances the sole, said knife standing stationary, while thefeed-wheel rotates, and an outside gage G, carried by the knife-supportand arranged in alignment with the knife in front of the feed-wheel,substantially as described. y

3. The combination, with the shaft B, the

IDO

feed-Wheel C, mounted thereon, and the inside gage J, of the plate E,mounted on the pin a, the outside gage G, the knife F, secured to saidplate, the arm e, the rod H, connecting said arm with the lever I, andthe spring g, acting on this lever, substantially as described.

4. The combination, with the shaft B, the feed-Wheel C, mounted thereon,and the inside gage J, of the plate E, mounted on the pin a, the outsidegage G, the knife F, secured to said plate, the arm e, the rod H,connecting said arm with the lever I, the spring g, acting on thislever, and the adjusting-screw h, substantially as described.

5. The combination, with the shaft B, the feed-Wheel C, mounted thereon,and the inside gage J, of the plate E, mounted on the pin a, the outsidegage G, the knife F, secured t0 said plate, the arm e, the adjusting-screw h,

and the locking-screw 7c, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.-

JACOB R. SCOTT.
